Definitions

  • the present invention is directed to a product display system, more particularly to a product display system that can be advantageously used to display bulk goods, and even more particularly to a pallet lifting device that can be advantageously used to display bulk goods that are positioned on a pallet.
  • the product display system of the present invention can be used to controllably lift and/or lower a pallet.
  • the pallet generally includes one or more items on the top surface of the pallet; however, this is not required.
  • Bulky goods such as, but not limited to, bags/cases of pet food, charcoal, bags of sand, bags of soil, bags of gravel, bags of pesticides, bags of salt, bags of fertilizers, bags of grass seed, bags/containers of cat litter, large bags of staple goods (i.e., flour, rice, sugar, beans, dried milk, etc.), cases of canned/bottled goods, cases of beverages, etc. are commonly sold to consumers while such bulky goods remain on the pallet.
  • staple goods i.e., flour, rice, sugar, beans, dried milk, etc.
  • This manner of selling goods to consumers commonly occurs at warehouse or discount stores (e.g., Costco, Marcs, BJ's, Sams Club, Kmart, Pet Smart, Petco, Target, Lowes, Home Depot, Mennards, etc.); however, other types of stores may also sell goods to consumers while the goods remain on a pallet.
  • these pallets of goods are placed on the floor of a store and consumers merely grab a bag/ bottle/container of the goods from the pallet of goods.
  • Some retailers attempt to hide the generally unsightly pallet by placing a frame or display about the pallet. These displays are generally 24"-40" high and include four sides to encircle the pallet. As can be appreciated, the shape, the number of sides, the height, etc. of such displays is non-limiting.
  • the display frame may also include advertising that provides information about the goods that are stacked on the pallet; however, this is not required.
  • advertising provides information about the goods that are stacked on the pallet; however, this is not required.
  • the height of the stacked goods decreases until eventually the top layer of bags is near the top edge of the display frame.
  • the top bag level is below the top edge of the display frame, the bag must be lifted over the edge of the display frame to remove the bag from the pallet of goods.
  • the display looks empty from a distance, thus may result in lost sales.
  • coiled spring pallet lifters In an attempt to address the issue of having to lift the bag over the edge of the display frame and/or the top bag being hidden by the top edge of the display frame, coiled spring pallet lifters have been developed. These coiled spring pallet lifters are designed to be in the fully raised/extended position when a certain low weight threshold exists on the top surface of the coiled spring pallet li fter. In practice, a pallet of goods is placed on the coiled spring pallet lifter, which results in the coiled spring(s) being compressed by the weight of the pallet.
  • a separate truck or hydraulic pallet lifter is required to lift the pallet of goods onto the top surface of the coiled spring pallet lifter, which height of the top surface of the coiled spring pallet lifter is about 20-40 inches when the coiled spring pallet lifter is in the fully raised/extended position.
  • the top surface of the coiled spring pallet lifter when in the fully raised/extended position can be less than or greater than 20-40 inches.
  • the weight of the pallet of goods reduces until the weight is such that the coiled spring(s) of the coiled spring pallet lifter are able to counter the weight of the pallet of goods, thus lifting the pallet of goods.
  • these coiled spring pallet lifters can be effective in raising pallets, such coiled spring pallet lifters are generally bulky, and require a truck or hydraulic pallet lifter to raise the pallet of goods onto the top surface of the coiled spring pallet lifter when the coiled spring pallet lifter is in the raised/extended position.
  • Many retailers do not allow a truck or large hydraulic pallet lifter on the retail floor, thus only allow the hand pulled pallet movers that only lift the pallet a few inches off of a floor surface.
  • Such hand pulled pallet movers do not and cannot raise a pallet high enough for loading the pallet of goods on a standard coiled spring pallet lifter when in the raised/extended position.
  • the pallet lifter of the present invention overcomes the past problems discussed above.
  • the pallet lifter is designed so that the top support surface can be manually or mechanically raised and lowered to be only a few inches above a floor surface so that a hand pulled pallet mover can easily load the pallet of goods onto the top support surface of the pallet lifter f the present invention.
  • the pallet lifter of the present invention includes a pallet platform, a lifting frame designed to raise and lower the pallet platform, and a movement mechanism designed to cause the lifting frame to move between an elevated or raised position and non-elevated position.

Abstract

L'invention concerne un chariot élévateur pour palettes pour monter et descendre des palettes. Le chariot élévateur pour palettes comprend une plateforme à palettes, un cadre élévateur qui soutient la plateforme à palettes et un mécanisme de mouvement qui fait monter et descendre la plateforme à palettes. La plateforme à palettes comprend une surface supérieure conçue pour soutenir une palette, deux parois latérales et une paroi arrière. Le cadre de levage comprend deux jeux de bras. Une extrémité d'un bras ou des deux bras de chaque jeu de bras est mobile le long d'un axe longitudinal de la plateforme à palettes lorsque la plateforme à palettes est levée ou abaissée. Le mécanisme de mouvement comprend un moteur électrique et une tige filetée. Le moteur électrique est conçu pour faire tourner la tige filetée dans le sens des aiguilles d'une montre et en sens inverse pour faire monter et descendre ladite plateforme à palettes.
